On the day that Vanille and Fang saved Gran Pulse from "The Fall", Lightning went missing. Everyone says that she never made it out of the crystal pillar, but Serah remembers her smile on that day. Meanwhile, Lightning has been tasked with guarding the goddess Etro form a mysterious man named Caius Ballad, who seems to want the collapse of time itself.

Every time you take part in a battle with a recruitable monster you have a chance to obtain their monster crystal, except if you already have their crystal. The exception to this is chocobo's. Once done, you can add them to your party through the Paradigm Pack and then insert them into your Paradigm Shifts.

The unfriendly monster you have to find is called Don Tonberry Its very rare and does only spawn in Bresha Ruins 100AF You can only reach this location towards the end of the game or after finishing the story Head through the blue gate in A Dying World 700AF requires 1 wild artefact to reach Bresha Ruins 100AF Stay in the area where the atlas bossfight took place in Bresha Ruins 005AF Run up and down the long path or keep running in circles Don Tonberry spawns about once every 20 minutes when you keep moving all the time Capturing him is also based on luck I had to defeat him 3 times before I captured his crystal without fragment skills You might need 10 tries if luck is not on your side Remember that its a black void that shows up when its Don Tonberry
